Description
Technical field
The utility model relates to automotive field, relates in particular to a kind of energy-efficient single-stage deceleration drive axle.
Background technology
Along with improvement and the raising of people to quality of the life requirement of highway in China condition, the design of singl-reduction axle is irreversibly towards low noise, lightweight, high efficiency future development, comfortable, safety, environmental protection, the efficient and energy-conservation main flow trend that becomes gradually development of automobile. But at present,, in major part, heavy truck is high by the maintenance cost of drive axle, transmission efficiency is low and energy consumption is higher, is not suitable with the development trend of high-velocity stream transport vehicle. Along with society is to environmental protection and energy-conservation pay attention to day by day, as the larger automobile product of energy resource consumption, especially in Medium or severe type truck field, the energy-saving and cost-reducing inexorable trend that has become development, and under Vehicles Collected from Market economic condition, high-velocity stream transport service development, user pursues high efficiency, high-quality, low cost, and this just proposes requirements at the higher level to aspects such as transmission efficiency, lightweight, reliabilities. And the important component part that drive axle transmits as automobile power, it is efficient, low power design is saved energy and reduce the cost and played key effect car load.
Utility model content
The deficiency existing for prior art, the purpose of this utility model is by a kind of energy-efficient single-stage deceleration drive axle is provided, and solves above-mentioned drive axle structure and assembling is complicated, maintenance cost is high, energy consumption is high, the technical problem that transmission efficiency is low.
A kind of energy-efficient single-stage deceleration drive axle, comprise axle case assy, main reducing gear, bonnet, brake and wheel end, described main reducing gear and bonnet are arranged on described axle case assy, one end of described axle case assy is connected with wheel end, described brake is two groups, be connected to the two ends of described axle case assy, described main reducing gear is little speed ratio main reducing gear, and described brake adopts wedge brake; The described end of taking turns is for non-maintaining bearing unit structure, described non-maintaining bearing unit structure comprises inner bearing and outer bearing, the sealing ring that described inner bearing and outer bearing are rectangle by cross section forms a groove, in described groove, is filled with lubricating grease, between described sealing ring, is provided with snap ring.
The spindle nose of described axle case assy is friction welding.
The housing of described axle case assy adopts high-strength steel sheet.
Thickness of shell≤the 14mm of described axle case assy.
