Description
Technical field
The invention belongs to Bus Technology field, specifically, relate to a kind of change speed gear box of passenger vehicle, particularly the connection structure of a kind of passenger train gear box and power-transfer clutch, and use passenger vehicle dynamic assembly and the passenger vehicle of this connection structure.
Background technology
In the design of passenger vehicle, the conveniently installation of driving engine, power-transfer clutch and change speed gear box, driving engine, power-transfer clutch and change speed gear box adopt compact arrangement structure usually, namely driving engine is directly connected with power-transfer clutch, the housing of power-transfer clutch is directly connected with the housing of change speed gear box (as shown in Figure 1 and Figure 2,1 " be change speed gear box, 21 " be clutch-bell cover), with the dynamic assembly making driving engine, power-transfer clutch and change speed gear box be integrally formed, convenient for assembly.The driving engine of passenger vehicle usually adopts three kinds of arrangement forms in car body, and namely driving engine is placed in car body rear end, driving engine is placed in the middle part of car body or driving engine is placed in car body front end.Engine at extreme rear and mid-passenger vehicle, at the poor easy generation high temperature of the cooling of Operation of Passenger Cars driving engine, and driving engine when breaking down slighter in the early stage chaufeur be not easy to hear, be not easy Timeliness coverage breakdown of equipment, the potential safety hazard to vehicle operating band; The passenger vehicle of engine behind front wheel is because driving engine is positioned at passenger vehicle front end, in passenger vehicle operational process, the air flowing that passenger vehicle advance produces can carry out cooling down to driving engine effectively, reduce breakdown in the motor rate, improve the life-span of driving engine, and driving engine is from the close together of chaufeur, the fault that chaufeur can occur in Timeliness coverage engine operation process, decreases potential safety hazard when passenger vehicle runs.
But, in the Bus & Coach Design of engine behind front wheel, driving engine is usually located at directly over front axle, because driving engine and change speed gear box size are comparatively large and be connected compact, take larger space, but also need designed engines cover cap, thus affect interior space and floor level, also make the layout of Das Gaspedal and gear box gearshift mechanism more difficult.And conveniently passenger is upper and lower in the design of passenger vehicle, require that in car, floor is lower as far as possible, especially urban bus, passenger's is more frequent up and down, could realize the upper and lower fast of passenger when only floor lower ladder round level is less in car.Management aspect conveniently chaufeur the passenger got on the bus supervised usually require that first passenger door should be opened before front-wheel, this just requires that in the car of passenger vehicle front end, floor is low, the passenger vehicle of engine behind front wheel is because driving engine is positioned at and takies larger space above automobile front-axle and cause that car Inner Front End floor level is higher, ladder round level is more, and inconvenient passenger is upper and lower fast.
Can be upper and lower fast in order to realize bus with front-mounted engine passenger, usually in the following way:
1. by driving engine, before change speed gear box is arranged in front axle, a kind of preposition long front overhang car chassis disclosed in Chinese patent CN2910728Y, comprise driving engine, change-speed box, vehicle frame, propons, wheel and suspension, before its driving engine is arranged on propons (i.e. the front axle of automobile), it is front that change speed gear box is arranged in propons (i.e. the front axle of automobile), although this scheme solves the technical matters that F/F vehicle realizes button fly front, but, because add the length of front overhang and driving engine and change speed gear box all arrange with propons before the front axle of automobile (i.e. before), cause the load of front overhang larger, make the load diatibution of car body uneven.
2. adopt independent front suspension, adopt independent suspension structure can save the front axle of vehicle to facilitate layout driving engine, can reduce the setting height(from bottom) of driving engine thus reduce floor level in car, but independent suspension structure is complicated, cost is higher.
Summary of the invention
The object of the invention is to the problem solving ground plate hight, driver zone narrow space in available engine front-mounted passenger car car, a kind of passenger train gear box is provided, the dynamic assembly with this change speed gear box is provided simultaneously, and there is the passenger vehicle of this dynamic assembly.
In order to realize object of the present invention, the invention provides a kind of passenger train gear box, technical scheme is as follows:
A kind of passenger train gear box, comprise the housing of change speed gear box, the housing of described change speed gear box has towards the front end face of driving engine, the front end face of described gear box casing is also provided with the adapter sleeve for connecting power-transfer clutch, the passage for passing for power transmitting elements is provided with in described adapter sleeve, the lower surface of described adapter sleeve and the front end face of described gear box casing form avoiding structure, and described avoiding structure is for the formation of to be on the downside of described adapter sleeve and accommodating passenger vehicle front axle on front side of described change speed gear box is horizontally through dodges space.By setting up adapter sleeve on gear box casing, the passage for passing for power transmitting elements is provided with in adapter sleeve, can clutch-bell cover be arranged on adapter sleeve, in the distance realizing increasing while power-transfer clutch and change speed gear box assemble between power-transfer clutch and change speed gear box, when making to assemble, operational space is larger, easy to assembly, also compactly arrangement structure is connected what realize ensure that while power-transfer clutch splits with change speed gear box, also change-speed box and power-transfer clutch can be made to be connected to become a rigid unitary by adapter sleeve, convenient lifting; Also be convenient to arrange the installation site of change speed gear box in car body, make driving engine and power-transfer clutch can be arranged on the front side of car body front axle, change speed gear box is arranged on the rear side of car body front axle, simultaneously because the lower surface of adapter sleeve and the surface of shell of transmission input are formed with avoiding structure, what this avoiding structure was horizontally through for the formation of accommodating passenger vehicle front axle dodges space, the front axle of passenger vehicle can run transverse through this and dodge space, thus reduce the setting height(from bottom) of power-transfer clutch and change speed gear box, solve ground plate hight in car, the problem that space, driver zone is little.
