Abstract
The utility model relates to a kind of automobile rear drive axle and includes a master gearbox, a differential gear, an axle shaft, drive axle housing assembly and a brake. The master gearbox is a single grade master gearbox with cone gear. The brake is a drum brake. The drive axle housing assembly includes a drive axle housing and a rear axle sleeve. The rear axle sleeve is equipped with inner bearings and outer bearings used for supporting hub. The transmission ratio of the master gearbox is 6.33. The diameter of the driven gear is 376.6mm. The utility model further optimizes the structure and dimension of rear drive axle parts so as to provide stable performance, reliable quality and high price to performance ratio.
Description
(1) technical field
The utility model relates to a kind of automobile rear driving axle.
(2) background technology
Farm vehicle is a transitional product in the Domestic Automotive Industry evolution, and its structure and performance use diesel engine to be used as power between automobile and trac..Because it relatively is fit to China's actual conditions, estimate that farm vehicle still has vast potential for future development in China rural area in 5～15 years of future.Continuous development along with rural economy and auto-industry, the farm truck market demand day by day increases, customer requirements is more and more higher, load-carrying capacity also requires to increase, the increase of farm vehicle recoverable amount is very fast in recent years, therefore reached 2,450 ten thousand by the year ends 2005, for example the demand of back axle etc. is very big to parts.
Rear driving axle is in the end of Power Train, its basic function is to increase the torque of being transmitted by transmission shaft or change-speed box, and power reasonably distributed to left and right driving wheel, also bear vertical upright, the longitudinal force and the transverse force that act between road surface and vehicle frame or the vehicle body in addition.Drive axle generally is made up of main reduction gear, diff, wheel drive and driving axle housing etc.Present back axle is being used for some problem below main existence the on the farm truck:
(1) the fault rate height of main reduction gear mainly shows as the master and is beaten tooth by dynamic bevel gear.
(2) hill climbing ability of car load is poor, and the fault rate height of semiaxis mainly shows as semiaxis and twists off.
(3) the axle housing distortion is big, and load-carrying capacity is little, and this also is to cause one of high reason of main reduction gear fault rate.
(4) brake efficiency is poor, and the braking temperature rise is too fast, and friction disc wear is too fast.
(3) utility model content
The purpose of this utility model is to provide a kind of stable performance, reliable quality farm vehicle rear driving axle.
Described farm vehicle rear driving axle, comprise main reduction gear, diff, semiaxis, driving axle housing assembly, drg, described main reduction gear is a conical gear formula single reduction final drive, described drg is a drum brake mechanism, described driving axle housing assembly comprises driving axle housing and axle tube, neck bearing, the outer bearing of support cage are installed on the described axle tube, and described main reduction gear transmitting ratio is 6.33, and the diameter of driven gear is 376.6mm.
Further, described driving axle housing sectional dimension be 110mm wide * the 130mm height, the diameter of axle of semiaxis is 50mm, the external diameter of axle tube is 75mm; Described neck bearing model is 30615, and described outer bearing model is 33115.
Further again, the sectional dimension of brake shoe brake cheek is φ 320 * 130mm in the described drum brake mechanism.This moment, the wearing and tearing of drg reduced, and had correspondingly prolonged its service life.
The utility model has been done further optimization to the structure and the size of each parts of rear driving axle, makes its stable performance, reliable in quality, the cost performance height.
(4) description of drawings
Fig. 1 is the cutaway drawing of embodiment 1 described farm vehicle rear driving axle.
(5) specific embodiment
The utility model is described in further detail below in conjunction with embodiment, but protection domain of the present utility model is not limited to this.
With reference to Fig. 1, a kind of farm vehicle rear driving axle, comprise main reduction gear 1, diff 2, semiaxis 3, driving axle housing assembly, drg, main reduction gear 1 is a conical gear formula single reduction final drive, drg is a drum brake mechanism, and the driving axle housing assembly comprises driving axle housing 4 and axle tube 5, and neck bearing 7, the outer bearing 8 of support cage 6 is installed on the axle tube 5, the main reduction gear transmitting ratio is 6.33, and the diameter of driven gear is 376.6mm.Driving axle housing 4 sectional dimensions be 110mm wide * the 130mm height, the diameter of axle of semiaxis 3 is 50mm, the external diameter of axle tube 5 is 75mm; Neck bearing 7 models are 30615, and outer bearing 8 models are 33115.The sectional dimension of brake shoe brake cheek 9 is φ 320 * 130mm in the drum brake mechanism.
Adopt the utility model respectively to optimize rear driving axle stable performance, the reliable in quality of size parts, cost performance height.
Claims (3)
