Summary of the invention
The purpose of this utility model is at the deficiencies in the prior art, provides a kind of reasonable in design, gear is many, ratio coverage is wide, differential little, big, the heavily loaded starting of car load of a retaining speed ratio, grade ability is strong, fuel economy is good single many gear vehicles of jack shaft speed changer.
The utility model is achieved through the following technical solutions:
A kind of single many gear vehicles of jack shaft speed changer, it is characterized in that: it is made up of interconnective major and minor speed changer, basic trnasmission comprise of being arranged in the main tank housing, with on same straight line two, two be provided with comprise one, a plurality of main tank synchronizers and the forward gear and the reverse gear of the synchronizer that reverses gear, two front ends are supported on by needle bearing in one the endoporus, and the rear end is connected with the main tank housing by bearing; In parallelly be provided with a jack shaft, jack shaft is connected with the main tank housing by bearing, driving gear on the jack shaft and a normal engagement, forward gear gear on the jack shaft is meshed with two the above forward gear gears, and the reverse gear on the jack shaft is meshed with two the above reverse gears by the idle wheel that reverses gear; Auxiliary transmission comprises the odd-side main shaft that is arranged on the odd-side housing, odd-side main shaft reduction gear be arranged on the odd-side jack shaft on the axle tooth be meshed, driving gear on the odd-side jack shaft is meshed with odd-side actuation gear on two, is provided with the odd-side synchronizer between odd-side actuation gear and the odd-side main shaft reduction gear; Connect by main tank top cover and the gas circuit between the odd-side cylinder that has two H operating mechanisms between the major and minor speed changer, realize linking by the main tank top cover and put into gear.
The utility model automotive transmission reverses gear and straight pin is set on the axle of carrier pulley of idle wheel, and the main tank housing is provided with corresponding lock groove, and the axle of carrier pulley that reverses gear is realized locking by the lock groove on straight pin and the main tank housing, prevents that reverse gear shaft from rotating and axial float.
Many gear vehicles speed changer of the present utility model is made of major-minor case speed changer, main tank top cover by having two H operating mechanisms between the major and minor speed changer and odd-side cylinder realize that major and minor speed changer interlock puts into gear, structural design is more reasonable, makes many gears transmission gear ratio wide ranges, differential little, big, the heavily loaded starting of car load of a retaining speed ratio, grade ability is strong, fuel economy good.
Description of drawings
Fig. 1 is the utility model example structure schematic representation.
Embodiment
Embodiment as shown in Figure 1, a kind of single jack shaft nine gear vehicle speed changers comprise interconnective major and minor speed changer, described basic trnasmission comprises that be arranged in the main tank housing 2 one 1, one is connected with main tank housing 2 by bearing; Be positioned at a right-hand member, be provided with two 3 with its same straight line, two be provided with comprise one, a plurality of main tank synchronizers and the forward gear and the reverse gear of the synchronizer 17 that reverses gear, two 3 front ends are supported on by needle bearing in one the endoporus, the rear end is connected with main tank housing 2 by bearing; In parallelly be provided with a jack shaft 4, jack shaft 4 is connected with main tank housing 2 with rear bearing by fore bearing, driving gear 15 on the jack shaft 4 and one 1 engagement often, forward gear gear on the jack shaft 4 is meshed with two 3 the above forward gear gears, and the reverse gear on the jack shaft 4 is meshed with two 3 the above reverse gears by idle wheel 5; Described auxiliary transmission comprises the odd-side main shaft 11 on being arranged in the odd-side housing 13, odd-side main shaft reduction gear 10 be arranged on odd-side jack shaft 9 on the axle tooth be meshed, odd-side jack shaft driving gear 16 is meshed with odd-side actuation gear 8 on two 3, is provided with odd-side synchronizer 12 between odd-side actuation gear 8 and the odd-side main shaft reduction gear 10.Connect by main tank top cover 7 and the gas circuit between the odd-side cylinder 14 that has two H operating mechanisms between the major and minor speed changer, realize linking by main tank top cover 7 and put into gear.
