Embodiment Construction

[0014] Below in conjunction with accompanying drawing, the present invention will be further described: as figure 1 As shown, the heavy-duty 10-speed transmission assembly is composed of the main box and the auxiliary box. It is characterized in that: the main box manually controls the 5 gears and adopts the gear shifting of the combination sleeve, and the auxiliary box pneumatically controls the 2 gears and uses the synchronizer to change gears. A total of 10 forward gears are formed; the 10-speed double countershaft transmission is equipped with a full helical gear structure for the auxiliary box, and the transmission can take power from the side, bottom of the main box or the rear end of the two intermediate shafts of the auxiliary box.

[0015] The tail end of the first shaft in the main box is connected with two shafts. The lower left and upper right positions of the second shafts are two identical and symmetrical intermediate shafts. The reduction gear on the intermediate...

Abstract

The invention relates to a heavy ten-gear speed changer assembly, which consists of a main box and a secondary box. The heavy ten-gear speed changer assembly is characterized in that five gears manually controlled by the main box adopt a combined sleeve for gear shifting, two gears pneumatically controlled by the secondary box adopt a synchronizer for gear shifting, and ten advancing gears are totally formed. A secondary box fully bevel gear structure is arranged on a ten-gear double-intermediate-shaft speed changer, and a speed changer can take force from the side surfaces and the bottom part of the main box or the back ends of two intermediate shafts of the secondary box. The invention reduces the gear shifting force, prolongs the service life of a synchronizer, and reduces the fault rate of the whole vehicle. The gears are clear, the gear shifting is flexible, a single H, a single lever, double levers and a flexible shaft can be adopted for operation, and the transmitted torque is increased so that the whole system is more reliable and durable. The invention has the advantages of large transmission torque, reliability, durability, smaller axial dimension and wide application range, and can be conveniently processed and produced.

Description

technical field [0001] The invention relates to a heavy-duty 10-speed transmission assembly, which belongs to the field of medium and heavy-duty vehicle transmissions. Background technique [0002] Currently, the most commonly used double-countershaft transmissions in the domestic medium and heavy-duty vehicle market are 8-speed, 12-speed, and 16-speed. The 10-speed double-countershaft transmission is only produced by a few companies and lacks innovation. In today's social background that emphasizes efficiency, energy saving and environmental protection, the transmission cannot meet the requirements of output torque and speed ratio range, as well as the requirements of higher reliability, durability and fuel economy. Contents of the invention [0003] The purpose of the present invention is to provide a heavy-duty 10-speed transmission assembly, which adopts the inclined double intermediate shaft structure. Large speed ratio, double countershaft 10-speed transmission asse...
