specific Embodiment approach

[0026] In order to further illustrate the technical solution of the present invention and its working process, in conjunction with the accompanying drawings, the specific implementation of the present invention is as follows:

[0027] Such as figure 1 with figure 2 As shown, the present invention provides a speedometer sensor installation assembly for motor-driven two-speed axles, the installation assembly is installed and connected to the two-speed reducer and differential assembly, and is used to adjust The odometer sensor is directly connected with the driving bevel gear in the two-speed reducer.

[0028] The installation assembly is composed of a rotational speed measurement joint 5, a sensor joint 3, an oil seal 4 and bolts 2;

[0029] Such as Figure 3a , 3b As shown in and 3c, the rotational speed measuring joint 5 is a short shaft structure, and from right to left, it is a threaded section, a shaft shoulder section, a smooth shaft diameter section and an axial slo...

Abstract

The invention discloses a speedometer sensor mounting assembly used for a motor-driven double-speed axle. The speedometer sensor mounting assembly used for the motor-driven double-speed axle comprisesa rotation speed measuring joint, a sensor joint, an oil seal and a bolt; one end of the rotation speed measuring joint is coaxially connected to the tail part of a driving bevel gear of a two-gear speed reducer through threads; an inserting groove is formed in the other end of the rotation speed measuring joint and connected with a shaft pin of a speedometer sensor; one end in the sensor joint is mounted in a cylindrical gear shell of the two-gear speed reducer and fixedly connected with the cylindrical gear shell of the two-gear speed reducer through a flange disc at the middle part; threads are arranged on the external circumferential surface of the other end of the sensor joint and connected with housing threads of the speedometer sensor; the oil seal is pressed into a step hole of the sensor joint; and the lip opening of the oil seal is mounted to be matched with the smooth shaft diameter section on the rotation speed measuring joint. According to the speedometer sensor mountingassembly used for the motor-driven double-speed axle, the speedometer sensor originally placed on the traditional automobile transmission is transplanted to the two-gear speed reducer and a differential assembly so that a vehicle speed measuring function of a motor driving axle is realized.

Description

technical field [0001] The invention belongs to the technical field of structural design of motor-driven axles of automobiles, and in particular relates to a speedometer installation assembly for motor-driven two-speed axles. Background technique [0002] With the application of new energy technology in the automotive field, the motor-driven two-speed reduction axle is gradually developed, that is, the motor is directly connected to the driver, and the traditional gearbox assembly structure is canceled or replaced. This change led to the cancellation of the speedometer originally arranged on the gearbox assembly, resulting in problems such as the inability to measure the speed of the car. Contents of the invention [0003] Aiming at the defects in the above-mentioned prior art, the present invention provides a speedometer installation assembly for motor-driven two-speed axles, which installs the original speedometer installed on the vehicle gearbox on the motor-driven two-...
