Abstract

A pre-and-post output foot-driving two-bit and eight-speed gear box comprises a 368Q speed transmission and a synchronizer. A 368Q engine part is joined with the pre-and-post output foot-driving two-bit and eight-speed speed transmission and then arranged on a main vehicle frame after being rotated at 90 degrees. The pre-and-post output foot-driving two-bit and eight-speed gear box is provided, thus, pre-and-post output can be used. Foot changing gears are shifted in an order of 1-N-2-3-4, and the two bits at high speed and low speed together with two-drive and four-drive conversion are suitable for the requirements of different working conditions. Increasing rotating speed of the engine, conversion between the two-drive and the four-drive, the two-bit conversion of pre-and-post output power and high speed and low speed are realized without changing the external size and weight of the engine assembly, thereby ensuring a dune buggy to meet the requirements when being used under different road conditions.

Description

Two eight-speed transmissions casees of front and back output foot-propelled

Technical field

The utility model relates to the dune buggy engine gearbox, particularly two eight-speed transmissions box assemblies of front and back output foot-propelled.

Background technique

At present, domestic beach buggy (ATV) all is two wheel drive, at the hole lowland, the quagmire front-wheel is unpowered is difficult to travel.Because beach buggy belongs to non-road running car, road conditions condition very severe, this just requires beach buggy will make not only that the driver handles steadily, safety, and requires four-wheel drive, makes that ATV can both be self-powered at each wheel of any road conditions.At present, beach buggy ATV middle small displacement engine on gearbox, still do not adapt to the engine mission of the forward and backward output power of multipurpose usage requirement.

Summary of the invention

The purpose of this utility model is exactly to realize that in the boundary dimension that does not change engine assembly and weight motor increases rotating speed, two drives, the 4 wheel driven conversion two transformations of forward and backward output power and high low speed.

The technological scheme that the utility model adopted is: it comprises 368Q speed changer and synchronizer, and the 368Q motor partly and after front and back export two eight speed automatic transmissions of foot-propelled and dock, is changeed 90 ° and loads onto main car frame.Wherein input shaft is that the I axle is that jack shaft connects by gear and II axle, and transmitting gear, III axle by the II axle again, to transmit gear Z37 be transition axis to the III axle, promptly fails spool to go out to connect in the back by gear and IV axle then, and the power of motor is outputed to next two wheels; Carrier gear on IV axle four-drive gear is promptly passed a bridge through the V axle is that front output shaft connects with forerunner's gear and VI axle, realizes that like this VI axle and the synchronous output power of IV axle are exactly four-wheel drive.The I axle connects with VII shaftgear on the VII axle by gear, and connects with the IV axle by IV axle reverse gear, realizes reverse gear like this.The combination of height reverse gear change lever connects with height reverse gear positioning work piece, and shows the conversion situation of height reverse gear position accurately by cross pan head screw, cold coiling pressure spring, steel ball.High speed synchroniser on camshaft high speed shift fork and the II axle and II axle IV shelves gear or II axle III shelves gear engagement, low speed synchronizer on camshaft low speed shift fork and the II axle and II axle II shelves gear or II axle I shelves gear link, can realize shift, change the forward velocity of vehicle.High speed synchroniser on tortoiseshell shift fork and the middle IV axle and II axle III shelves gear or low speed gear link, to realize the high and low speed position.The tortoiseshell shift fork also with middle IV axle on high speed synchroniser and IV axle reverse gear link, to realize the reversing of vehicle.High speed synchroniser, forerunner's gear on the combination of 4 wheel driven transducer and 4 wheel driven shift fork and the VI axle link, to realize four-wheel drive.

Advantage of the present utility model mainly contains:

1, the pin shift is simple to operate, flexible, safe, reliable,

2, two of high low speed change and two drive, the 4 wheel driven conversion, the ATV grade ability of travelling is strengthened greatly;

3, two drivings, 4 wheel driven move and can change at any time according to the road surface situation;

4, two transformations of high low speed can realize the low-speed big needs smoothly;

5, do not increase engine weight;

6, changing motor output turns to;

Two eight-speed transmissions of output foot-propelled before and after the utility model gearbox has, output before and after adopting, the pin shift is pressed 1-N-2-3-4 shelves order shift, two transformations of high low speed and two are driven, the 4 wheel driven conversion adapts to different working condition requirements, this gearbox has 8 forward gearss, a neutral gear, a reverse gear.Realize that in the boundary dimension that does not change engine assembly and weight motor increases rotating speed, two drive, the 4 wheel driven conversion, two transformations of forward and backward output power and high low speed.Satisfied the usage requirement of beach buggy under various road conditions.
