Patent number: 7311633Abstract: A vehicular drive unit comprises a central differential mechanism and a front-wheel side axle differential mechanism. The central differential mechanism comprises a first planetary gear train 10, which includes an output gear body 50, a first carrier 13, which is provided in a one-piece body with this gear body, a first sun gear 11, a first ring gear 14, and a rear-wheel drive gear 15, which is a helical gear formed around this ring gear in a one-piece body. In this drive unit, a differential limiter C is provided between the output gear body 50 (input rotating member) and a drive gear body 55 (output rotating member) to generate a rotational resistance, which acts to reduce the rotational difference between the output gear body 50 and the drive gear body 55.Type: GrantFiled: December 20, 2005Date of Patent: December 25, 2007Assignee: Honda Motor Co., Ltd.Inventors: Taiji Maruyama, Kanji Kita, Mikihiro Takano, Kazunori Miyata

Patent number: 6726591Abstract: The four-wheel drive system for vehicles has a center differential mechanism that divides the rotational driving force from the engine E between the front and rear wheels, and a front wheel side axle differential mechanism that divides this divided rotational driving force between the left and right front wheels. The center differential mechanism is constructed from a single pinion type first planetary gear device which has a first carrier 13 that receives the rotational driving force from the engine E, a first sun gear 11, and a first ring gear 14 that is connected to the rear wheel side, and the axle differential mechanism is constructed from a double pinion type second planetary gear device which has a second ring gear 24 that is connected to the first sun gear 11, a second sun gear 21 that is connected to the right front wheel, and a second carrier 23 that is connected to the left front wheel. The first and second planetary gear devices are disposed adjacent to each other in a coaxial configuration.Type: GrantFiled: July 15, 2002Date of Patent: April 27, 2004Assignee: Honda Giken Kogyo Kabushiki KaishaInventors: Taiji Maruyama, Tetsurou Hamada, Kanji Kita

Patent number: 6213241Abstract: A hydraulic coupling device includes left and right vane pumps which discharge working oil in response to the relative rotation of main driven wheels and left and right subsidiary driven wheels. First orifices are defined in a side plate disposed between the left and right vane pumps to permit communication between intake ports and discharge ports in the vane pumps. Orifices are defined in the side plate to permit communication between the intake ports and between the discharge ports in the vane pumps. With the above arrangement, in a hydraulic coupling device of a power transmitting system in a four-wheel drive vehicle, the formation of the orifices can be easily carried out, and the characteristics of the orifices can be stabilized.Type: GrantFiled: October 14, 1998Date of Patent: April 10, 2001Assignee: Honda Giken Kogyo Kabushiki KaishaInventors: Kanji Kita, Takuya Kurokawa

Patent number: 5951401Abstract: Tripod joints, each of which includes revolvable rollers to be directly fitted to outer circumferential surfaces of spider shafts, are provided respectively at both ends of an input-side shaft to which slave driving force is transmitted. Accordingly, it is possible to prevent a slave driving system from transmission of unnecessary torque, and obtain a slave driving force-transmitting mechanism which is compact and light in weight, having a structure simplified as compared with those of the conventional technique.Type: GrantFiled: December 31, 1996Date of Patent: September 14, 1999Assignee: Honda Giken Kogyo Kabushiki KaishaInventors: Kanji Kita, Shigeo Kurita, Yasuhiro Kawashima, Tohru Mabuchi, Takeji Shino
