Problems solved by technology

The torsion spring in the above-mentioned patent is a double torsion spring connected by two springs, and the middle part is a fixing part of a ring structure. The torsion spring only relies on a fastening bolt to fix the fixing part on the guide block, and its installation is difficult. To ensure precise positioning, the double torsion spring will deform during the operation of the valve train, which will adversely affect the reliability of the system

Abstract

The invention aims to provide a double-torsion spring mounting bracket and a manufacturing method thereof, ensuring that a double-torsion spring can be favorably positioned and installed on a guide block so as to improve the reliability of a valve lift control system. The double-torsion spring mounting bracket comprises a tabular main body provided with a mounting hole, wherein the front part of the main body is provided with a catch vertical to the main body; a first vertical thrust plate is respectively arranged below two sides of the main body; the rear part of the main body is connected with an affiliated plate which is parallel to the main body and is positioned below the main body; the affiliated plate is provided with a hole corresponding to a mounting hole; a second vertical thrust plate is respectively arranged below two sides of the affiliated plate; and a front vertical thrust plate is arranged below the front part of the affiliated plate. The double-torsion spring mountingbracket has the advantages of simple structure, low cost and simple manufacturing technology and convenience for installation.

Description

technical field [0001] The invention belongs to the technical field of internal combustion engine manufacturing, and more specifically, the invention relates to a torsion spring mounting bracket of a novel variable valve lift gas distribution mechanism and a manufacturing method thereof. Background technique [0002] With rising oil prices and increasingly stringent emission regulations, engines with low pollution, low fuel consumption, high power, and high torque have become the mainstream trend of engine design, and variable valve technology has gradually become popular. Patent CN200910116666.2 discloses a valve lift control mechanism that can realize stepless adjustment for internal combustion engines, which can realize fully variable valve lift and meet the requirements of different engine working conditions for valve lift and opening time. The camshaft in the valve lift control mechanism is installed on the bearing seat of the engine cylinder head. The engine cylinder ...
