Description

Technical Field

[0001] This utility model relates to a special mounting bracket for a tractor combination motor. Background Technology

[0002] The applicant's prior patent application, with publication number CN223203598U and titled "A Tractor Combined Motor and Gearbox Assembly," describes a tractor combined motor in the field of range-extended tractor technology. The motor consists of a generator and an electric motor. The mechanical energy of the engine is first converted into electrical energy by the generator, which then drives the electric motor. The electric motor drives the tractor through the transmission gearbox. This method can achieve many advantages such as smooth shifting and low fuel consumption.

[0003] Currently, tractor combination motors, consisting of a generator and an electric motor, can be purchased directly from the market. However, designing a dedicated mounting bracket that allows the tractor combination motor to be securely installed on the bracket, while also facilitating quick connection between the tractor combination motor and the power source (engine) and the power transmission component (tractor combination motor gearbox assembly), is a technical challenge that the applicant currently faces and needs to solve. Utility Model Content

[0004] To address the shortcomings mentioned above, this utility model provides a dedicated mounting bracket for a tractor combination motor.

[0005] To achieve the above objectives, this utility model provides a dedicated mounting bracket for a tractor combination motor, comprising a bracket housing, a flywheel housing connecting flange fixed to the front end of the bracket housing, and a motor cover fixed to the upper part of the bracket housing. The bracket housing, the flywheel housing connecting flange, and the motor cover together enclose a mounting cavity for the tractor combination motor. The length of the mounting cavity is equal to the length of the tractor combination motor to restrict the forward and backward movement of the tractor combination motor within the mounting cavity. The bracket housing is also equipped with multiple third bolts, which are screwed onto the outer housing of the tractor combination motor to restrict the circumferential rotation of the tractor combination motor.

[0006] As a further improvement to the design, a fourth bolt is provided on both the inner and outer sides of the housing frame. The fourth bolt is screwed onto the outer housing of the tractor combination motor on the inner and outer sides, respectively, thereby further ensuring the stability of the tractor combination motor after installation.

[0007] As a further improvement to the solution, a front positioning pin is provided on the front side of the tractor combination motor, and a rear positioning pin is provided on the rear side of the tractor combination motor. The end face of the flywheel housing connecting flange is formed with a first pin hole that matches the front positioning pin, and the end face of the housing frame is formed with a second pin hole that matches the rear positioning pin.

[0008] As a further improvement to the design, the housing frame also forms a transfer chamber in the lower part of the mounting cavity. A rotatable front output shaft of the transfer chamber is arranged inside the transfer chamber. The front end of the front output shaft of the transfer chamber extends out of the transfer chamber and passes through the flywheel housing connecting flange, and is connected to the front drive axle through a universal joint drive shaft. A four-wheel drive output spline sleeve is arranged on the rear end of the front output shaft of the transfer chamber. The housing frame also has an assembly hole corresponding to the position of the four-wheel drive output spline sleeve, so that the four-wheel drive input shaft of the tractor combined motor gearbox assembly can be inserted through the assembly hole and plugged into the four-wheel drive output spline sleeve.

[0009] As a further improvement to the design, the inner cavity of the transfer chamber stores lubricating oil, and a drain bolt is provided at the bottom of the transfer chamber.

[0010] As a further improvement to the solution, the housing frame and the flywheel housing connecting flange are fixedly connected by a plurality of first bolts, and the flywheel housing connecting flange is connected to the engine located on the front side by a plurality of second bolts.

[0011] As a further improvement to the solution, the tractor combined motor includes a generator and a motor. The cable connectors and cooling water connectors of the generator and motor are centrally arranged at the top of the tractor combined motor. The upper part of the motor cover has holes for the cable connectors and cooling water connectors to extend out.

[0012] As a further improvement to the solution, a torsional damper is configured at the front end of the generator's input shaft. After the flywheel housing connecting flange is connected to the engine by the second bolt, the torsional damper is connected to the engine's flywheel to achieve power transmission.

[0013] The advantages of this utility model over the prior art are as follows: the special mounting bracket has a compact and reasonable structural design, and the tractor combination motor can be stably installed inside it. At the same time, after installation, the connection between the tractor combination motor and the engine and the tractor combination motor gearbox assembly is very convenient. The cable connector and cooling water connector located on the upper part of the motor cover can be easily connected to the external circuit and cooling water pump. In addition, the configuration of the front output shaft of the transfer case is connected to the front drive axle, and the clutch of the tractor combination motor gearbox assembly can be controlled to realize the switching between rear drive and four drive modes of the tractor.
