AI Technical Summary
When there are two or more traditional oil pumps, air pumps, and water pumps, the power transmission through pulleys is inefficient, has a large radial force, increases size and cost, and requires a speed reducer when the motor drives the equipment, which increases cost and axial length, and is difficult to manufacture.
Design a multi-output reducer with a clutch, which achieves at least two outputs through one input gear, integrates the clutch into the output gear, utilizes the output gear and bearings to reduce the size and cost of the equipment, and uses a pneumatic piston device as the actuator to simplify the connection structure.
This has resulted in reduced cost and size of multi-output reducers, optimized equipment layout, and eliminated the need for additional bearing housings and shift fork structures, thereby reducing processing difficulty and cost.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of machinery, and in particular to a multi-output reducer with a clutch. Background Technology
[0002] In the field of special-purpose vehicles such as sanitation vehicles and construction machinery, traditional upper-body equipment such as oil pumps, air pumps, and water pumps, when there are two or more upper-body equipment, often use pulleys to install multiple pulley sets axially on the output shaft. The transmission of power by pulleys is not only inefficient, but also results in large radial forces, requiring additional bearing housings. This arrangement increases the size and cost.
[0003] With the development of new energy vehicles, motor-driven superstructure equipment has become the mainstream. Currently, motor-driven superstructure equipment consists of pulleys and power take-offs at both ends of the motor. Without a reducer, the motor torque is high and the cost is high; if a reducer is added, both ends need to be increased, increasing cost and axial length; if only one reducer is added, a through shaft is required, increasing the processing difficulty. Utility Model Content
[0004] The purpose of this invention is to provide a multi-output reducer with a clutch, which can achieve at least two outputs with one input, thereby reducing costs, decreasing size, and facilitating equipment layout.
[0005] The technical solution of this utility model is as follows: a multi-output reducer with a clutch, including a housing and an input gear, a first output gear and a second output gear disposed in the housing. The first output gear is provided with a first clutch, and a first output flange is provided on the right side of the first output gear to achieve separation and engagement with the first output gear via the first clutch.
[0006] Furthermore, the first clutch includes a first mounting hole axially disposed within the first output gear, a first return rod disposed within the first mounting hole, a return mechanism disposed on the first return rod, and a first connecting member fixed to the right end of the first return rod for cooperating with the first output flange, the first connecting member being slidably connected to the first output gear via a spline.
[0007] Furthermore, the return mechanism includes a first retaining ring disposed in the middle of the first mounting hole, the left side of the first retaining ring abutting against a first limiting plate, the left end of the first return rod having a large diameter end, the first return rod passing through the first limiting plate and being fitted with a first return spring located between the large diameter end of the first return rod and the first limiting plate.
[0008] Furthermore, a first actuator is coaxially disposed on the left side of the first return rod, and the left end of the first return rod cooperates with the first actuator via a first end face bearing.
[0009] Furthermore, the first actuator is a pneumatic piston device.
[0010] Furthermore, the right end of the first connector is provided with a first end face tooth, the first output flange is rotatably connected to the housing, and the left end of the first output flange has a second end face tooth that nests with the first end face tooth when the first connector slides to the right.
[0011] Furthermore, the input gear, the first output gear, and the second output gear are all rotatably connected to the housing, and the first output gear and the second output gear mesh with the input gear respectively.
[0012] Furthermore, a second clutch with the same structure as the first clutch is provided inside the second output gear, and a second output flange is provided on the right side of the second output gear to achieve separation and engagement with the second output gear via the second clutch.
[0013] Furthermore, a second actuator is provided on the left end housing of the second clutch.
[0014] Furthermore, an output shaft is provided at the right end of the input gear to form a three-output speed reduction device.
[0015] Compared with the prior art, the present invention has the following advantages:
[0016] 1. This multi-output reducer can achieve two or three outputs with one input, which not only reduces costs and size, but also facilitates equipment layout.
[0017] 2. By integrating the clutch into the output gear, the output gear and corresponding bearings are fully utilized, which not only further reduces costs but also further reduces size.
[0018] 3. Since the first actuator and the clutch are coaxial and located at the axial center, a smaller planar thrust bearing can be used at this connection point, eliminating the need for a shift fork, which is difficult and costly to manufacture.
[0019] 4. The force required for the push-pull connector is small, so the spring force of the first return spring is small. Also, since it is in the center position, the friction between the first actuator and the first return rod can be ignored. Attached Figure Description
