Abstract
The invention discloses a synchronizer of an auxiliary automobile gearbox. The synchronizer comprises a tooth hub (1), a tooth sleeve (2) and a transmission shaft, wherein the tooth sleeve (2) is sleeved on the outer surface of the tooth hub (1); the surface of the inner ring of the tooth hub (1) is provided with a standard involute spline tooth groove (3); and one end of the transmission shaft is inserted into the inner ring of the tooth hub (1) and is connected with the standard involute spline tooth groove (3). The synchronizer of the auxiliary automobile gearbox expands the comprehensive application functions of the automobile gearbox and the synchronizer and is particularly applicable for light-weighted transporting vehicles in hilly areas; meanwhile, the connecting strength is improved and the torsion bearing capacity of the transmission shaft is enhanced; the synchronizer of the auxiliary automobile gearbox is flexible in operation and convenient to maintain; and the gearbox has relatively strong advantages in economy and practicality.
Description
Technical field
The present invention relates to a kind of automotive transmission odd-side synchronizer.
Background technique
Light transportation vehicle is because vehicle is little, and the operation tune is convenient, uses flexibly, and vast farmers friend enjoy a lot.But the difference of the road conditions in rural area is bigger, and cement road, hill path also have dirt road, rolling country light transportation vehicle load climbing to seem gruelling, the outlet pipe over-emitting black exhaust.LG520 odd-side synchronizer is applied to odd-side behind the speed changer, loads onto the transmission assembly of 520 high and low shift odd-side synchronizers, makes original gear 5+R become 2 reverse gears of 10 forward gearss, ratio coverage is big, and it is many to handle function of use, particularly climbing, driving is steady, and fuel-economizing is laborsaving.
Summary of the invention
The invention provides a kind of automotive transmission odd-side synchronizer, it has not only enlarged automotive transmission and synchronizer is used comprehensive function, be particularly suitable for the use of rolling country light transportation vehicle, strengthen the intensity when connecting simultaneously, improved the moment of torsion bearing capacity of rotatingshaft, manoeuvrable, easy to maintenance, no matter be the Economy of speed changer, practicability has all manifested bigger advantage.
The present invention has adopted following technological scheme: a kind of automotive transmission odd-side synchronizer, it mainly comprises tooth hub, tooth cover and transmission shaft, the tooth cover is enclosed within the outer surface of tooth hub, the inner peripheral surface of described tooth hub is provided with standard involute splines teeth groove, and described transmission shaft one end penetrates in the inner ring of tooth hub and links with standard involute splines teeth groove.
The inner peripheral surface of described tooth hub is provided with the connection that matches with transmission shaft of 30 standard involute splines teeth groove; Described tooth hub one end face is a concave structure, and the other end is provided with twice V-type oil storage trap; The outer surface of described tooth hub is provided with 39 standard involute splines teeth, is provided with 39 standard involute splines teeth groove in the inner ring of described tooth cover, and the standard involute splines teeth groove in the standard involute splines tooth of described tooth hub outer surface and the tooth cover inner ring is slidingly matched; The appearance of described tooth cover is provided with fork slot; The material of described tooth hub and tooth cover is the 20CrMnTi Alloy Constructional Steel.
The present invention has following beneficial effect: automotive transmission odd-side synchronizer of the present invention is applied to the configuration of automotive transmission odd-side, handle fork shift by the odd-side synchronizer, whole automotive transmission ratio coverage is expanded to be twice, suitable especially vehicle in the rolling country or during climbing gear select, driving steadily, fuel-economizing is laborsaving, and is safe and reliable.One end face of tooth hub of the present invention is a concave structure, has so both controlled the engagement rigging position of tooth hub on transmission shaft, optimizes the odd-side design, guarantees the engagement width of tooth cover and tooth hub simultaneously.Have 30 standard involute splines teeth groove in tooth hub inner peripheral surface, strengthen tooth hub and rotatingshaft linking intensity, improve the moment of torsion bearing capacity of rotatingshaft, meet the requirement of standardized designs, use flexibly, easy to maintenance.Odd-side synchronizer hub sleeve of the present invention is 20CrMnTi alloy structure material, has both improved the intensity of tooth hub and tooth cover, the toughness that keeps relative stability again, and wear and shock-resistant, and material source is abundant, and price is suitable.
