Description
Technical field
The present invention proposes a kind of gear assembly of electric wheel motor suspension, is related to electric vehicle technical field.
Background technology
Electric wheel be one kind by motor-driven integrated wheel technology, the core of principle is by driving motor and its biography
Dynamic device is integrated with wheel, forms independent vehicle function part.Electric wheel, which has, to be simplified vehicle structure, improves vehicle traveling
The advantages that performance, is widely used in the vehicle structure that wheel independently drives.
Its common power delivery mode of existing electric wheel has direct joint transmission and flexible coupling joint transmission.
Direct joint transmission is the fixed axis transmission form being fixed on driving motor on axletree, simple in structure, is easy to
It realizes.But since driving motor rigidly fixes on axletree, driving motor is synchronized with wheel bears road shocks, damage
The service condition of motor, destroys the stability and reliability of transmission.
Flexible coupling joint transmission is the increase flexible coupling component between driving motor and hub for vehicle wheel, typical
Mode is sliding cross coupling, can realize under the operating mode that the axis relative position between motor driving and wheel changes, drive
Dynamic motor continues to transmit torque to wheel.Disadvantage is that sliding cross coupling sliding stroke is limited, high-torque, height
There is impact under speed conditions, sliding block is easy to wear.
Further, existing motor technology cannot still reach power and the torque that needs are directly driven in vehicle wheel, subtract using
In the case of speed variator, it is further added by flexible driving coupling arrangement, faces the extreme difficulties of space limitation in wheel.
Therefore, the big retarding under the conditions of unsteadiness of wheels is adapted to than the method and apparatus that can be driven in roller, is electric wheel
Technology development need solves the problems, such as.
Invention content
The purpose of the present invention is to propose to a kind of gear assemblies of electric wheel motor suspension, realize the big of wheel internally-powered
Reduction ratio and its reliable and stable transmission effectively promote the torque output capability of electric wheel.
The technical solution adopted in the present invention：The gear assembly of electric wheel motor suspension is by driving motor, two-stage
Dead axle taper gear pair, a prismatic pair are constituted, it is characterised in that：Driving motor is suspended at wheel semiaxis or is fixed on vehicle frame axis
On, and be connected with first order gear pair；Both the output gear of first order gear pair and the input gear of second level gear pair
Axis overlaps, and the transmission shaft of the two constitutes prismatic pair along the axis；The output gear shaft and vehicle wheel of second level gear pair
Hub is fixedly connected.
The output gear shaft of the first order gear pair and the connecting mode of the input gear axle of second level gear pair can
For the axis of inside and outside spline fitted pattern or polygonal cross-section, set cooperation pattern.
The gear assembly of existing electric wheel driving motor suspension compare the beneficial effects of the invention are as follows：
（1）The present invention is based on two-stage dead axle Bevel Gear Drives, pass through the sliding pair of the transmission shaft between two-stage gear drive
Connecting mode realizes the transmission problem that conventional flex mechanism could solve.Make wheel using fixed axis gear transmission mechanism
Meanwhile and realizing the mutual decoupling that torque drive is moved with wheel with road vibration.
（2）The sliding pair connecting mode of the present invention has mechanism configuration identical with common dead axle transmission mechanism and sky
Between be laid out, therefore compact overall structure.Therefore, the present invention had not only realized big retarding ratio, Large-torsion transmisson, but also improved in wheel and pass
Dynamic stability and reliability, is effectively improved the service condition of motor.
In existing electric wheel actuation techniques, there is not yet the method for the above technological invention, scheme or device.
