Abstract: A solenoid switch for a vehicle starter is disclosed, which comprises a housing defining an axial direction; a cap carrying a pair of contact studs, the cap having a front end which is fixed in the housing; a solenoid core mounted in the housing in front of the cap; and an elastic element having a maximum (extreme) allowance compression in the axial direction, the elastic element being compressed between the cap and the solenoid core in the axial direction by an elastic pre-compression amount which is smaller than the maximum allowance compression; wherein the solenoid core is supported by the housing at its front side and is supported by the elastic element at its back side. A vehicle starter comprising such a solenoid switch is also disclosed. Axial bouncing of the cap can be reduced by the invention.

Abstract: An engaging device and a starter comprising the engaging device, the starter comprises an electric motor, a speed reducer connected with the electric motor, an overrunning clutch comprising a driving piece connected with the speed reducer and a driven piece, and an engaging device with a main shaft connected with the driven piece of the overrunning clutch. A quick engagement may be achieved and a certain initial engagement depth is guaranteed. During the engaging process, the pinion may mesh into a ring gear in its own initiative, reducing the effect of teeth milling phenomenon on the ring gear to a maximum extent.

Abstract: The present invention relates to a combined end cap and an electromechanical device equipped with the combined end cap. The combined end cap includes: an end cap body, which includes a fitting portion provided with a first mating portion; and an end cap flange, which is configured to have at least two segments adapted to be combined and mounted to the fitting portion, and at least one of the segments is provided with a second mating portion adapted to corporate with the first mating portion to prevent the segments having been combined and mounted to the fitting portion from rotating relative to the fitting portion. The application of this invention can not only significantly improve the versatility and convenience of the existing end caps, but also help to reduce the manufacturing cost.

Abstract: A motor, and a starter for a vehicle including a motor are described. The motor includes an excitation coil and a thermal element. The excitation coil is electrically connected with the bus terminal through which current flows when the motor is in operation. The bus terminal has a thermal contact surface. The thermosensitive element is fixed onto the bus terminal and has a collection surface in thermal contact with the thermal contact surface. The motor is provided with a thermal protection function.

Abstract: A window lifter device for driving a motor to control the up and down motion of an automobile window includes: a switch assembly; an up driving circuit for driving the motor to move up the window; a down driving circuit for driving the motor to move down the window; and a control circuit directly coupled between the switch assembly and the up and down driving circuits for controlling the up driving circuit to drive the motor to move up the window when the switch assembly is in a manual up operating state, and controlling the down driving circuit to drive the motor to move down the window when the switch assembly is in a manual down operating state.

Abstract: An overload-protection and damper device for a vehicle starter is disclosed, the starter comprising an electric motor and a planetary-gear type speed reducing mechanism coupled with an output shaft of the electric motor. The overload-protection and damper device comprises a ring gear of the speed reducing mechanism, the ring gear having an outer circumference of a frusto-conical shape and defining an axial direction, a holder ring for receiving the ring gear therein, the holder ring having an inner circumference of a frusta-conical shape, with the outer circumference having a cone angle which is substantially equal to that of the inner circumference, and an elastic element applying an axial pushing force to the ring gear towards the holder ring so that the outer circumference biases against the inner circumference, forming a frictional fit therebetween. An increased maximum output torque can be provided by a simple structure.

Abstract: A solenoid switch for a vehicle starter includes a housing defining an axial direction and a circumferential direction, a cap carrying a pair of contact studs, a solenoid core mounted in the housing in front of the cap, and an elastic element clamped between the front end of the cap and the solenoid core. The housing defines first retention portions at first circumferential with the first retention portions being separated from each other in the circumferential direction. The front end of the cap is fixedly clamped at the first circumferential locations between the first retention portions and a flange which is formed by radially inwardly crimping a back end of the housing. The front end of the cap is pushed against the flange by the elastic element at second circumferential locations each defined between two neighboring first circumferential locations. A vehicle starter includes the solenoid switch.
