Embodiment Construction

[0011] figure 1 An exemplary machine 10 is shown, such as a wheel loader. Machine 10 may include a front portion 12 and a rear portion 14 that are pivotally connected to each other by hitch assembly 15 . Rear section 14 may include cab assembly 1 , engine (not shown) and driveline components (not shown), all mounted on main frame 18 . The front section 12 may include a frame assembly 22 and a work implement 24 connected to the frame assembly 22 by a linkage including a boom (boom) 26 and a lift cylinder 28 .

[0012] refer to figure 2 The frame assembly 22 may include a lift cylinder bracket 30 pivotally receiving the lift cylinder 28 and two support members 29 connected to the lift cylinder bracket 30 . The frame assembly 22 may also include a base plate 34 which, together with the lift cylinder bracket 30, forms a cavity 36 through which lift cylinder control lines or hoses (not shown) may pass.

[0013] refer to image 3 , the lift cylinder bracket 30 may include a li...

Abstract

The present invention discloses a bracket for a lifting jar, including a lifting jar support and a basal component fixedly mounted on the lifting jar support. The basal component may include a first segment and a second segment extending with a certain angle from the first segment.

Description

technical field [0001] The present invention generally relates to a bracket assembly, and more particularly relates to a lift cylinder bracket assembly and a manufacturing method. Background technique [0002] The engineless frame of a wheel loader typically includes a subassembly with a bracket for receiving a hydraulic lift cylinder of a work tool. The engine-less frame assembly also includes a window panel with a large opening through which lift cylinder control wires or hoses can pass. Typically, the lift cylinder bracket and window panel are manufactured as separate components and welded together at the level without the engine end frame assembly. This manufacturing method requires the manipulation of multiple components, resulting in high manufacturing costs. Additionally, the lift cylinder bracket may include structures that must be machined at the height of the frame assembly without the engine end, further increasing manufacturing costs. [0003] A method of maki...
