Description
Technical field
The utility model belongs to the durable bearing cap knot of new-energy automobile accessories field more particularly to a kind of new-energy automobile
Structure.
Background technology
In recent years, including the new-energy automobile of pure electric vehicle and hybrid vehicle comes into being, and combines high performance drive
The fusion of dynamic motor and control technology, energy storage technology, material technology has played electric vehicle real-life efficient
Rate, environmental protection, it is energy saving, light the advantages that.Electric vehicle solves the crisis of the energy and the pollution of environment, in the process of technological innovation
In, it is contributed to alleviating the crisis of Global Auto industrial finance and energy environment issues Zhuo.
Bearing cap is a large amount of universal components of new-energy automobile, although not being big component, the role and influence of bearing cap
It is very prominent：Keep bearing orientation correct, is further ensured that the concentricity between itself depth of parallelism of transmission shaft and each axis is good；This
It is extremely crucial for the stable operation of new-energy automobile.And light based on new-energy automobile, flexible feature, one side torque become
Changing may be very fast, and transmission needs high efficiency, therefore opposite fuel vehicle has different requirements.
In order to meet the high request in these performances, it is made to ensure the stability of axis, bearing cover it is improved important
Property is self-evident.
Utility model content
Purpose of utility model：The utility model proposes a kind of new-energy automobile durable bearing cover, it is relatively traditional
Bearing cap carries out the optimization in structure, to solve problems of the prior art.
Utility model content：A kind of durable bearing cover of new-energy automobile, includes the lid and cover board of integrally connected,
The lid, cover board are in hollow cylindrical, and center is provided with the axis hole of perforation, and the axis hole inner edge is axially provided with keyway, lid
The diameter of plate is more than the diameter of lid, and the lid is circumferentially provided with the mounting hole of several perforations, and the lid has around axis hole
There is the block structure of several protrusions.
Preferably, the keyway is axially provided with 1 ~ 3 along axis hole inner edge.The quantity that keyway opens up makes its key coordinate
When it is secured and reliable.
Further, also there is step in the keyway.The setting of step allows key to coordinate by different level, closer.
Preferably, the axis hole near outer ends are also provided with inside groove circle.The setting of inside groove circle make axis and shaft hole matching when
Time stays gap, has cushion space.
Preferably, the outer of the lid is also provided with outer groove circle in the position close to cover board.Outer groove circle loss of weight, changes simultaneously
Become the distribution of force of lid portion outside.
Preferably, the mounting hole is circumferentially uniformly distributed 4 ~ 8 in lid.The quantity of mounting hole keeps its fastening reliable.
Preferably, the block structure is uniformly distributed 3 ~ 4 around axis hole, and forming quantity is identical between block structure
Structure grooves.The distribution of block structure strengthens axis the stability of the mating connection bearing of cover board side.
Compared to the prior art, the beneficial effects of the utility model are：The utility model is simple in structure, cooperation is firm,
It is durable.Lid, cover board hierarchical design and open the axis hole of perforation, keep axis and axis hole contact surface larger；The setting of keyway, block structure
Axis, bearing it is two close reliable to being connected, stability is excellent；The setting of inside groove circle, outer groove circle makes whole loss of weight, and
Having on stress distribution influences, and the inertia run after making axis coordinate more meets the requirement of electric vehicle；Block structure, structure grooves have
Buffering, scavenging action.The utility model is more refined compared to the bearing cover of fuel-engined vehicle, passes through slot to cooperation, hole
Optimization design, axis hole and axis contact surface are larger, more more stable than the bearing cap of traditional common, durable, meet the machine of electric vehicle
Tool performance requirement.
