Technical field
The utility model relates to a kind of farm vehicle rear driving axle.
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.Along with the continuous development of rural economy and auto-industry, the farm truck market demand day by day increases, and customer requirements is increasingly high; Load-carrying capacity also requires to increase, and farm vehicle recoverable amount increase in recent years is very fast, has reached 2,450 ten thousand by the year ends 2005; Therefore very big to the parts demand, back axle for example.
The rear drive vehicle bridge 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 axle housing etc.Present rear drive vehicle bridge is being used for some problem below main existence the on the farm truck:
(1) fault rate of main reduction gear is high, 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 of semiaxis is high, mainly shows as semiaxis and twists off.
(4) the drg temperature rise is too fast, and friction disc wear is too fast, and brake efficiency is poor.
The utility model content
The purpose of the utility model is to provide the farm vehicle that a kind of hill climbing ability is strong, maintenance rate is little rear driving axle.
The utility model has adopted following technical scheme:
A kind of farm vehicle rear driving axle, it comprises axle case assy, main reduction gear, diff, semiaxis, drg, wheel hub brake drum assembly, said axle case assy comprises axle housing, axle tube, stop pin; Said main reduction gear is a conical gear formula main reduction gear; Main gearbox assembly is connected with axle housing through bolt, and described drg is a drum brake mechanism, and brake assembly is connected with axle housing through bolt; Said wheel hub brake drum assembly comprises brake wheel, rear-wheel hub; Brake wheel is connected with rear-wheel hub through wheel bolt, and rear-wheel hub is connected with semiaxis through bolt, and rear-wheel hub is connected through semiaxis with main gearbox assembly; Said axle tube is provided with neck bearing, outer bearing; The diameter dimension of the driven gear of said main reduction gear is set to 325～330mm, and the diameter of axle size of semiaxis is set to 45～50mm, and the outside dimension of axle tube is set to 65～75mm.
Preferably, the diameter dimension of the driven gear of said main reduction gear is set to 325.77mm.
Preferably, the diameter of axle size of said semiaxis is set to 45mm.
Preferably, the outside dimension of said axle tube is set to 75mm.
Preferably, the brake shoe brake cheek sectional dimension of said drg is set to φ 320 * 130mm.
A kind of farm vehicle rear driving axle of the utility model beneficial effect is:
(1) diameter dimension of the driven gear of the utility model main reduction gear is set to 325.77mm, and actv. has prevented that the master of main reduction gear from being beaten the tooth phenomenon by dynamic bevel gear, reduced the fault rate of main reduction gear.
(2) diameter of axle size of the utility model semiaxis is set to 45mm, and the outside dimension of axle tube is set to 75mm, and actv. prevents the phenomenon that semiaxis twists off, and has improved the hill climbing ability of car load.
(3) the brake shoe brake cheek sectional dimension of the utility model drg is set to φ 320 * 130mm, and actv. has prevented that the drg temperature rise is too fast, and the situation that friction disc wear is too fast has improved brake efficiency.
