Problems solved by technology
[0003] Bearing brackets are often used in electric vehicles. The structure of the bearing brackets currently used is relatively complicated, and the bearings will generate a lot of heat during long-term operation. The mechanical properties will be deteriorated due to thermal expansion and contraction, and sometimes Breakage, if breakage occurs during use will cause serious accidents

Embodiment Construction
[0019] Such as Figure 1 to Figure 7 As shown in the figure, a special electric vehicle rear axle lubricating connection fitting is used in conjunction with the electric vehicle rear axle lubrication structure to better lubricate the important parts of the electric vehicle rear axle structure assembly, so that the electric vehicle rear axle The structure has better stability during use and longer service life. The structure of this part is simple and the production cost is low, which can make the lubrication effect of the lubrication structure better, and can reduce the cost of the lubrication structure as a whole, thereby reducing the aftermath of electric vehicles. The cost of using the bridge structure during its use. It includes a cylindrical main body connection support column 1, and a cylindrical central avoidance connection hole 2 is provided at the center of the upper end of the main body connection support column 1, and this position is connected with the main lubrica...

The invention relates to the technical field of electric automobiles, in particular to a special electric automobile rear axle lubrication connecting accessory. According to the adopted technical scheme, the special electric automobile rear axle lubrication connecting accessory comprises a cylindrical body connecting supporting column, and a cylindrical center position avoiding connecting hole isformed in the center position of the upper end of the body connecting supporting column; the left side and the right side of the body connecting supporting column are provided with symmetric arc clamping assembling connecting arc grooves correspondingly, and arc center axes of the clamping assembling connecting arc grooves are arranged on the outer cylinder face of the body connecting supporting column; and the center position of the lower end of the center position avoiding connecting hole is provided with an inverted-cone-shaped center connecting lubrication hole penetrating a whole component. The center position, close to the lower end, of the left side of the outer cylinder face of the body connecting supporting column is provided with a cylindrical auxiliary lubricating connecting hole. The special electric automobile rear axle lubrication connecting accessory has the beneficial effects that the component structure is simple, the production cost is low, the lubricating effect of alubricating structure can be better, and the cost of the lubricating structure can be integrally reduced.
Description
technical field [0001] The invention relates to the technical field of electric vehicles, in particular to a special lubricating connection fitting for the rear axle of the electric vehicle. Background technique [0002] An electric vehicle is a vehicle that uses a battery as an energy source, and converts electrical energy into mechanical energy through controllers, motors and other components to control the current and change the speed. The first electric car was produced in 1834 and it was driven by a DC motor. Today, electric vehicles have changed dramatically and come in many varieties. Among them, an electric vehicle (EV) refers to a vehicle powered by an on-board power supply, driven by a motor to drive the wheels, and conforms to the requirements of road traffic and safety regulations. Due to its smaller impact on the environment than traditional cars, its prospects are widely optimistic. [0003] Bearing brackets are often used in electric vehicles. The structure...
