Description
Technical field
The utility model relates to the parts of beach buggy, is specifically related to a kind of beach buggy chain stay.
Technical background
The chain stay of beach buggy mainly is responsible for and is welded on respectively chain stay and is responsible for the chain stay axle sleeve and the anchor ear at two ends and forms by two parallel chain stays, chain stay is responsible for and is generally rectangular tube, be provided with the back damping that rear shock absorber is installed between two chain stays are responsible for journal stirrup is installed, axially offer opening in the anchor ear bottom along anchor ear, opening part is provided with holds bolt tightly.As shown in Figure 4 and Figure 5, the anchor ear of existing beach buggy chain stay is a cylindrical shape, two chain stays are responsible for and are welded on the anchor ear middle part, there is following defective in the anchor ear of this structure: one, because anchor ear is the cylindrical metal member, anchor ear is embraced on the rear-axle casing of beach buggy, and the contact surface between itself and the rear-axle casing is bigger, so need very big power rear-axle casing could be held tightly, screwing when holding bolt tightly, certainly will increase labor intensity of operating personnel like this; Two, because being responsible for, two chain stays are welded on the anchor ear middle part, the power that chain stay is applied on the anchor ear will tangentially all act on anchor ear one side (chain stay and anchor ear weld side) along anchor ear, anchor ear will be subjected to bigger pull power and making anchor ear produce deformed damaged easily, and because beach buggy is subjected to the impulsive force of vertical direction in the process of moving often, make the weld seam between the chain stay person in charge and the anchor ear produce very big stress, and produce fracture easily herein, thereby influence the quality of beach buggy.
The utility model content
The purpose of this utility model provides a kind of beach buggy chain stay, makes anchor ear on the chain stay stressed rationally and be easy to rear-axle casing is held tightly.
Beach buggy chain stay described in the utility model, comprise that two parallel chain stays are responsible for and are welded on respectively chain stay axle sleeve and the single radial cut anchor ear that chain stay is responsible for two ends, axially offer opening in the anchor ear bottom along anchor ear, opening part is provided with holds the bolt group tightly, two chain stays are responsible for the first half that is welded on anchor ear, and anchor ear offers breach and opening and connects in the both sides of opening.
Beach buggy chain stay described in the utility model, because two chain stays are responsible for the first half that is welded on anchor ear, the power that chain stay is acted on the anchor ear is decomposed into two parts, a part along anchor ear radially, another part is tangential along anchor ear, diametral load will not born and can be exerted an influence to anchor ear by rear-axle casing, and make anchor ear produce deformed damaged, and what make that weld seam on it produces stress is described tangential force, because this tangential force only acts on the part of the power on the anchor ear for chain stay, so the stressed generation of anchor ear distortion, with and on the stress that produces of weld seam all reduced significantly, make anchor ear stressed rationally.Because offer breach and opening connects in the both sides of anchor ear opening, breach offer the area of contact that has reduced anchor ear and rear-axle casing, make anchor ear be easy to rear-axle casing is held tightly, reduce operating personal and screwed the labour intensity of holding bolt tightly, simultaneously, the position that also can utilize breach the to vacate lubricating oil of in rear-axle casing, annotating.

The specific embodiment
As shown in Figure 1 to Figure 3, this beach buggy chain stay comprises that two parallel chain stays are responsible for 2 and be welded on chain stay axle sleeve 1 and the single radial cut anchor ear 4 that chain stay is responsible for 2 two ends respectively, it is rectangular tube that chain stay is responsible for 2, be provided with the back damping between two chain stays are responsible for 2 journal stirrup 5 is installed, axially offer opening in anchor ear 4 bottoms along anchor ear, opening part is provided with two and holds bolt group 3 tightly, the two chain stays person in charge 2 is welded on the first half of anchor ear 4, the cylindrical of its upper surface and anchor ear (4) is tangent, anchor ear 4 offers arc (or rectangle) breach 6 and opening perforation at two middle side parts of opening, makes two to hold the both sides that bolt 3 is positioned at this breach 6 tightly.
Claims (3)
1, a kind of beach buggy chain stay, comprise that two parallel chain stays are responsible for (2) and are welded on chain stay axle sleeve (1) and the single radial cut anchor ear (4) that chain stay is responsible for two ends respectively, axially offer opening in the anchor ear bottom along anchor ear, opening part is provided with holds bolt group (3) tightly, it is characterized in that: two chain stays are responsible for the first half that (2) are welded on anchor ear (4), and anchor ear (4) offers breach (6) and connects with opening in the both sides of opening.
2, according to the described beach buggy chain stay of claim 1, it is characterized in that: described breach (6) is arc or rectangular indentation.
3, according to claim 1 or 2 described beach buggy chain stays, it is characterized in that: the described chain stay person in charge's (2) the upper surface and the cylindrical of anchor ear (4) are tangent.
