Abstract
The utility model discloses a vehicle slow running stepless speed change device, which comprises a vehicle running gearbox and a running driving axle. The device is characterized in that a driving force switching gearbox is arranged between the vehicle running gearbox and the running driving axle; the vehicle running gearbox is connected with the driving force switching gearbox through a high-speed running driving shaft; the driving force switching gearbox is connected with the running driving axle through a transmission shaft, and is connected with a stepless speed change driving motor through a slow running driving shaft; and the driving force switching gearbox switches a vehicle driving force between the high-speed running driving shaft and the slow running driving shaft. The vehicle slow running stepless speed change device has a simple structure and convenient mounting, and can realize stepless speed change of a vehicle from zero speed within a certain speed range.
Description
Technical field
The utility model relates to a kind of automobile low-speed running continuously variable unit, belongs to the automobile repacking technical field.
Background technology
A lot of engineering special-use vehicles need be run at high speed when transition, and need be with very slow speed walking when construction operation, in order to realize this purpose, prior art is to increase to adorn an auxiliary gearbox after the automobile traveling change speed gear box, its shortcoming is a step change, can not realize the stepless change in certain speed range of starting from scratch, and can not satisfy the requirement that vehicle is walked under utmost point jogging speed, the big cost height of auxiliary gearbox volume in addition, difficulty in installation and layout.
The utility model content
Technical matters to be solved by this invention is, overcome the technological deficiency that prior art exists, provide a kind of vehicle when transition, to run at high speed and begin stepless change and automobile low-speed running continuously variable unit easy for installation in certain speed range from zero velocity can be at construction operation the time.
The utility model automobile low-speed running continuously variable unit, comprise vehicle to run change speed gear box (automobile gearbox) and walking drive axle (automobile rear driving axle), it is characterized in that: between vehicle to run change speed gear box and walking drive axle, propulsive effort teeth change roller box is set, the vehicle to run change speed gear box is connected by the high speed propel driving shaft with propulsive effort teeth change roller box, propulsive effort teeth change roller box connects the walking drive axle by transmission shaft, and propulsive effort teeth change roller box connects the CD-ROM drive motor (HM Hydraulic Motor or electric notor) of continuously variable by the low-speed running axle drive shaft; Propulsive effort teeth change roller box can switch vehicle drive force between high speed propel driving shaft and low-speed running axle drive shaft.
Described propulsive effort teeth change roller box, driving driven gear by casing, switching shift fork, low-speed running driving driving gear and low-speed running forms, low-speed running drives driving gear and is installed on the low-speed running axle drive shaft, low-speed running drives driven gear and is installed on the driven shaft, switches shift fork and can stir the switching engagement between transmission shaft and low-speed running driving driving gear of low-speed running driving driven gear.
The utility model automobile low-speed running continuously variable unit, simple in structure, easy for installation, can realize that vehicle begins stepless change in certain speed range from zero velocity.
Description of drawings
Fig. 1, the utility model automobile low-speed running continuously variable unit structural representation;
Fig. 2, be the birds-eye view of Fig. 1;
Fig. 3, propulsive effort change gear box structure scheme drawing of the present utility model.
The specific embodiment
Below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail.
Embodiment: the automobile low-speed running continuously variable unit, between vehicle to run change speed gear box 1 and walking drive axle 5, a propulsive effort teeth change roller box 3 is set exactly, teeth change roller box 3 is fixed on the vehicle frame 2.Propulsive effort teeth change roller box 3, driving driven gear 15 by casing 12, switching shift fork 13, low-speed running driving driving gear 17 and low-speed running forms, low-speed running drives driving gear 17 and is installed on the low-speed running axle drive shaft 16, and low-speed running axle drive shaft 16 is power driven by HM Hydraulic Motor 11.Low-speed running drives driven gear 15 and is installed on the driven shaft 14, and driven shaft 14 connects walking drive axle 5 by transmission shaft 4, to the vehicle transmission of drive force.The end of the high speed propel driving shaft 9 that vehicle to run change speed gear box 1 drives is installed on vehicle to run change speed gear box 1 casing, and is relative with transmission shaft 4.Switch shift fork 13 and can stir the switching engagement between high speed propel driving shaft 9 and low-speed running driving driving gear 17 of low-speed running driving driven gear 15, thereby realize the switching of vehicle to run power.When being power with HM Hydraulic Motor 11, when walking, can make vehicle begin stepless change in certain speed range, therefore from zero velocity by low-speed running axle drive shaft 16 powered vehicle, vehicle can travel with extremely slow speed, to satisfy the working requirement of engineering truck.
The propulsive effort of automobile low-speed running is not limited to HM Hydraulic Motor in the utility model, and other technical schemes of only doing the power replacement still belong to claimed scope of the present utility model.
