Engine cylinder block structure of automobile transmission

Abstract

The invention discloses an engine cylinder block structure of an automobile transmission. The engine cylinder block structure of the automobile transmission comprises an aluminum alloy shell. A cylinder barrel is arranged at the upper end of the aluminum alloy shell. A cylinder sleeve is arranged on the inner wall of the cylinder barrel. A cooling water jacket is arranged on one side of the cylinder sleeve. The cooing water jacket is in an open type. The portions, between the cylinder barrel and the cooling water jacket, of the two sides of the cylinder barrel are provided with installation threaded grooves. Flatness detection columns are connected into the installation threaded grooves in a threaded manner. A hierarchical structure is arranged inside each flatness detection column and iscomposed of a non-wear top layer, a slight-wear layer, an intermediate-wear layer, an intermediate-deep-wear layer and a deep-wear layer, wherein the non-wear top layer, the slight-wear layer, the intermediate-wear layer, the intermediate-deep-wear layer and the deep-wear layer are sequentially arranged from top to bottom. Since the multiple groups of flatness detection columns are evenly distributed at the upper end of the aluminum alloy shell and located on the periphery of the cylinder sleeve, the wear degree is distinguished through observation of the color depth of the flatness detectioncolumn on each point during later-period detection, and overhauling and detection are convenient.

Description

technical field [0001] The invention relates to the technical field of automobile gearbox engines, in particular to an automobile gearbox engine cylinder structure. Background technique [0002] The gearbox mainly refers to the gearbox of the car, which is divided into manual and automatic. The manual gearbox is mainly composed of gears and shafts, and the variable speed and torque are generated through different gear combinations; It is composed of torque converter, planetary gear, hydraulic pitch change system and hydraulic control system. Variable speed and torque are achieved through hydraulic transmission and gear combination. The functions are: 1. to change the transmission ratio; 2. to enable the car to run backwards when the engine rotation direction remains unchanged; PTO. [0003] The engine is an important part of the gearbox. During the use of the cylinder block of the engine, the metal shell surface of the cylinder block is easily worn, so it needs regular ma...
