Abstract
The invention discloses a driving wheel assembly and an engine front gear train using the same. The driving wheel assembly comprises a mounting rack assembly and a friction wheel, the friction wheel is mounted on the mounting rack assembly through a bearing, the mounting rack assembly comprises a mounting board and a bracket, the mounting board is hinged with one end of the bracket through a connection pin, and the other end of the bracket is connected with the friction wheel. The engine front gear train using the driving wheel assembly comprises a crank pulley and an accessory pulley, the driving wheel assembly is mounted on the engine via the mounting rack component or the mounting board, and the friction wheel of the driving wheel assembly contacts with the belt on the crank pulley and the accessory pulley. For the engine front gear train, with the driving wheel assembly, power is transmitted by the friction wheel, the conventional belt and tensioning mechanism are eliminated, the increase of axial size for meeting the requirement of belt driving is not needed, and for the engine with two belts at the front gear train, the advantage is particularly evident.
Description
Technical field
The present invention relates to engine art, the motor head train that is specifically related to a kind of drive wheel assembly and adopts this drive wheel assembly.
Background technique
The front end train of motor car engine is that the automobile auxiliary system that comprises water pump, generator and steering pump provides power, and the motor head train generally adopts the pattern of many wedges belt, tensioning mechanism tensioning to carry out transmission of power at present.As shown in Figure 3; For adopting two bel-drivenn motor head trains; For satisfying band transmission requirement, often must increase the axial dimension of crank pulley 3, satisfy the requirement of sheathed wedge belt more than two 4,7 on crank pulley; So increased the size of engine system, be unfavorable for the requirement of motor miniaturization.
Summary of the invention
The object of the present invention is to provide a kind of drive wheel assembly of the effect that realizes belt and tensioning mechanism and the motor head train that adopts this drive wheel assembly, effective transferring power reduces the axial dimension of motor head train.
A kind of drive wheel assembly that is used for the motor head train of the present invention comprises scaffold assembly and friction wheel, and said friction wheel is contained on the scaffold assembly through bearing, is used for transferring power between the wheel of motor head train and belt.
Further, said scaffold assembly comprises mounting plate and support, and said mounting plate is used for being connected with motor, and an end of mounting plate and support is hinged through connecting pin, and the other end of support connects friction wheel.
Said mounting plate is fan-shaped mounting plate, which is provided with mounting hole and waist-shaped hole.
Further, described mounting plate is provided with adjusting portion.
The agent structure of said friction wheel is a metal, and its surface is provided with abrasive rubber.
A kind of motor head train that adopts described drive wheel assembly; Comprise crank pulley and accessory belt pulley; Between crank pulley and accessory belt pulley, be provided with said drive wheel assembly, said drive wheel assembly is installed on the motor through scaffold assembly or mounting plate.
Further, the friction wheel of this drive wheel assembly contacts with belt and accessory belt pulley on the said crank pulley.
Beneficial effect of the present invention is: through the setting of this drive wheel assembly; Make crank pulley pass through friction wheel, removed belt and tensioning mechanism in the past, so this motor head wheel ties up to when designing to the accessory belt pulley transferring power; Just need not strengthen axial size for the requirement of satisfying the band transmission; For the motor of two belts of front end train layout, this advantage is particularly evident, so this drive wheel assembly has brought feasible condition for the motor miniaturization.
